Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

Spatio‐Temporal cGAN Based Channel Estimation for Low‐Altitude Integrated Sensing and Communication Systems

Electronics Letters, Volume 62, Issue 1, January/December 2026.
Reliable channel estimation in low‐altitude ISAC is challenged by UAV‐induced fast‐varying and non‐stationary channels. We present an ST‐cGAN framework that jointly models spatial and temporal features under conditional adversarial learning, achieving superior accuracy and robustness compared with conventional and deep learning baselines.
